How TWIGA will improve heavy rain forecast in Africa

The prediction of heavy rainfall is a critical issue in several countries. In Africa, the scarcity of data to support such predictions makes it fundamental to improve the monitoring of atmospheric parameters. TWIGA researchers will set up a system that exploits satellite images and in-situ measurements to derive useful data for meteorological agencies to improve the prediction of heavy rain. The images will be captured by radar sensors on board of the European Space Agency (ESA) Sentinel Satellites.

The in-situ measurements will be derived from low-cost GPS (Global Positioning System) instruments, the same embedded in our smartphones, currently mainly used for navigation purposes.
